PRODUCT DESCRIPTION
This innovative nitrous oxide plate system offers all the advantages of Nitrous Express' renowned Billet Crossbar systems, but with a revolutionary twist.
Stealth Installation
Unlike traditional nitrous oxide plate systems, the Covert Crossbar installs discreetly INSIDE the intake manifold, rather than on top of it. This unique design means you no longer need to invest in costly hoods or modify your existing one. The Covert Crossbar plate allows for a completely hidden nitrous oxide system, with the nitrous and fuel inlets strategically located on the back of the plate, pointing towards the firewall for maximum discretion.
Precision Engineering
While installation requires machining of the intake manifold, Nitrous Express has you covered. We provide comprehensive instructions to guide you through the machining process. We also offer a convenient machining and plate installation service for those seeking professional assistance.
Unrivaled Distribution
The Covert Crossbar ensures optimal nitrous and fuel distribution and atomization, delivering consistent and powerful results every time. NX Crossbar nitrous plates feature a meticulously engineered spray pattern that guarantees precise nitrous and fuel mixing injected into the runners. This precise distribution provides a more uniform mixture to each cylinder, resulting in enhanced combustion efficiency and maximum horsepower.
Key Features:
Stealth Design: The plate sits below the carburetor, eliminating the need for hood modification and remaining hidden. Nitrous and fuel inlets are located on the back of the plate, pointing towards the firewall.
Uncompromised Performance: Delivers the same horsepower and reliability as our standard Billet Crossbar systems.
Experience the ultimate combination of hidden power and flawless design. Ideal for those who want to maintain a sleek, unaltered appearance for their vehicle while enjoying unbeatable performance.
